Ba星系统的星风吸积及污染因子刘俊红和仲池田文生摘要：用整个系统的角动量守恒条件代替切向动量守恒条件，且δr≠0，考虑轨道偏心率的高次项，推导了星风吸积质量及轨道参量变化方程。

Nature, most elements have two or more isotopes, the same kinds of elements in the quality of the various isotopes of different, but the types and proportion constant (except for radioactive elements). In 1961, the carbon content of the most abundant in nature, a kind of isotope, carbon-12 atom of a quantity and quality of C as a 12 mass units to it as "benchmarks" for all isotopes of an element according to the average abundance The ratio of the benchmark is the atomic weight of this non-prime, that is listed in the periodic table of atomic weights.

自然界中大多数元素都有两种或更多的同位素，同种元素的各同位素质量不同，但其种类和比例是恒定的。1961年，把碳在自然界含量最丰富的一种同位素，碳12的一个原子的质C量定为12个质量单位，把它作为"基准"，某种元素的所有同位素按丰度的平均值与基准之比，就是这种无素的原子量，即元素周期表列出的原子量。

Uranium isotope abundance ratio has been measured by total sample evaporation and signal integration, and a thermal surface ionization mass sepctrometry equipped with multicollector has been used.

采用全蒸发技术、离子流强度积分的方式，用多接收器热表面电离质谱计测量铀同位素丰度。

The results showed that the most of epizoie parasites identified in rhesus monkeys were louse and acarid. A large quantity of nits were observe in the cases of louse infection, while a mass of scurfs were formed in monkey infected by acarid.
